PRODITER WITH kCOOLING- WTER JACKET.

Application led July 9, 1924, Serial No. 725,068, and in GermanySeptember 15V, 1921.

This invention relates to a producer With In producers the coolingWaterrjacketis exposed to strong 'Wear as it is submitted from theinside to the action of the air-containing cooling Water and from theoutside to the erosive actions of coke and slag dust. Consequentlyleakages occur frequently Which give cause for ivearisoniedisturbancesof service. As the repairing of a defective cooling Water jacket is`diflicult and requires much time owing to the commonly used form ofconstruction of sucli cooling Water jackets the entire cooling Waterjacket has yto'be exchanged after a short time'of service, Which israther expensive and the more so as the producer has to be stopped for along time.

According yto this invention the' abovementionedY inconveniences areavoided vby constructing the cooling jacket of interchangeable,exchangeable Water cooled boxes independent of one another, ysaid boxesbeing of substantially trapezoidal cross section and arranged to form acomplete cooling jacket. 'lhe several boxes are constructed so that theyare shut off from one another; they have each a separate inlet andoutlet for the cooling vvaterconnected vviththe main pipes so'that theycan be easilyl disconnected from the same. The cooling jacket segmentscan for instance consist of cast bodies With serpentine coolingchannels. The exchangeability can be facilitated by the use of wedgepieces inserted from the inside and serving.V

for securely Vl'iolding the boxes in position. These Wedge pieces arepressed against the adjacent elements of the cooling jacketby means ofscrew bolts accessible from the, outside. Y y y v If for each segment aseparate outflow for the' coolingjvater is provided, Which freelyterminates into'an open discharge conduit, it is possiblev todetermineatevery moment whether the circulation of the cooling Water Y is normal,so that disturbances in the supplyl of cooling water or leakage fromindividual segments can be found out soon-v ,enough to prevent seriousdamages.

' 'Several embodiments of the invention.. are

shown byvvay of example in the accomp'anying drawing, in Which F ig. 1shows one A,form of construction in vertical longitudinal section, thesection being taken on the line l-lofFig. 2.

Fig. 2 is a horizontal cross section on the line 11-11 of Fig. 1.

' Figs. 3 and t are vertical'and horizontal J sections respectivelyrepresenting a second form ofl construction, the sections being taken onthe lines indicated.

` AAccording to Figs. l and v2, the producer Y' comprises a permanentouter Wall consisting of an outer envelope c and an inner layer of boxesduit y In the second form `of construction vsho'vvn f in Figs. 3 and 4,respectively,rthe cooling jacket is 'composed of the castelements 'nhaving each a serpentine cooling channel o.

The elements n are wedged apart and pressed Vboxes 7c from' an annularpipe d `With Which Y ythe Water boxes are connected` byVV tubularvconnecting pieces g of which each one has a valve 7. The Water flowsout from the Water Y ,7c throughp'ipes h'into lan open conagainst thepermanent outer Wall of the producer by means of Wedge'pieces lZ andscrevv bolts m. Water is admitted from, annular pipe d through valves fandpipes yg to the .lower ends vof channels o through which it lpassesupwardly and out through pipes h finto open conduit z'. l

In both-forms of construction the cooling elements are of'such breadththat they Vcanv be easily inserted through a sight hole (not shown)inthe top of thefurnace. f

We claimz- In a furnace having a permanentv outer 9'5 y Y' Wall, acooling Water jacket forming the in# ner lining of `the furnacecomprising independent Y segments, means forVV conducting Water throughsaid segments', the adjacent edges of the segments dvergng toward theinterior of the furnace, Wedge shaped members interposed between saiddvergng edges, and means for drawing said Wedge VShaped members rewardsaid permanent outer Wall t0 clamp said segments to said Wall.
